The unique art style perfectly complements the narrative and atmosphere, creating an immersive, nostalgic experience that blends surreal and grounded environmental details. While not graphically intensive, the visuals stand out for their charm, cohesiveness, and ability to evoke a specific era's vibe, delighting fans of 90s/00s aesthetics.
- “The graphics of this game are very much meant to harken back to early 2000s PC games with Y2K futurism aesthetic, with the UI and in-game technology looking very much like “blobjects” you would’ve seen at the time.”
- “I think Panthalassa did a perfect job capturing the weird and uncanny feel of those 90s 3D graphic adventure games, while also having a different theme for the narrative; it's like a very whimsical submerged world with some deep cerebral and introspective undertones.”
- “The aesthetic and soundtrack in Panthalassa are insane for such a tiny team; really scratches my itch for 90s/00s CRT & Frutiger aero visuals and old techno music.”
